A continuous random variable, X, is found to be uniformly distributed over the interval 4≤x≤9. What is the probability that a number randomly chosen from this interval is in the interval 3≤x≤8? Give the notation of the distribution and the notation of the probability that would be calculated.

The correlation coefficient, r, can be used to decide if data has a strong linear relationship. We always have -1≤r≤1{“version”:”1.1″,”math”:”-1≤r≤1″} .  What values of r  indicate the strongest linear relationship to the data. (Select all statements that indicate a strong linear relationship.)
